php.ini changes not taking

I have a php.ini issues with a php4.3, Solaris 8, Apache 1.3.27 machine. as well as a php4.3, RedHat 8, Apache 1.3.27 I have changed the php.ini file that phpinfo is pointing to, and restarted apache(sometimes stop, wait, and start) and i never see the changes take place in phpinfo. The settings i am specifically trying to change are register_globals = On; (i'm on an internal network with these boxes, so i'd like to set to On to minimize upgrade hassles with older lazy coding). session.bug_compat_42 = 0 session.bug_compat_warn = 0 furthermore i have completey removed and renamed php.ini from that directory. stopped and started apache and phpinfo still displays the same information, even when a valid php.ini does not exist. does PHP have an internal cache with all of this info stored in it?? if so how can i clear it to get the changes. Is there another way to force these changes to take place. I have found some old threads about this in the archives and their issue seemed to be resolved by killing the main apache pid and starting apache. I have also tried this with no success. Thanks for any assistance you may have. Jeff
